I'm not sure this is really about share of services in the economy, but rather wealth/confort (both correlated of course). When you look at Pew data for attitudes towards social media, you have a similar pattern despite it being no threat to the services sector.

High-services/low-AI-optimism countries (US, France, Australia) are also the social-media skeptics, while lower-services/high-AI-optimism countries (Mexico, India, Brazil, Indonesia) are social-media optimists. And Singapore is the consistent exception, i.e. service-heavy yet optimistic on both.

So "comfortable, wealthy populations are tech-skeptical" seems like a more likely explanation to me.
